Application filed August 9, 1916. Serial No. 113,921.

T 0 all whom it may concern.'

Be it known that l, ALBERT H. CARRIER, a citizen of the United States, residing at Asheville, in the county of Buncombe and Sta-te of North Carolina, have invented new and useful Improvements in Casements, of which the following is a specication.

The present invention relates to improvements in easement mountings and the pr`1- mary objects of the invention are to provide an improved mounting for the sash and improved means for mechanically moving the sash into diderent desired positions, whereby the sash may be swung into open position for ventilation, it may be swung into a position which will enable the sash to be cleaned easily and from the inside, and it may be swung into a position parallel to the wall of the building, or substantially so, and thus avoid forming an obstruction at the outside of the building, all these movements of the sash being accomplished with facility and ease by the aid of the mechanical operating means for the sash, which operating means may further serve to lock the sash in its closed or any other desired position.

A further` object of the invention is to provide a easement wherein the sash is capable of the movements described and which also embodies means for swinging or operating the sash mechanically, and yet the easement may be made at reasonable cost, installed in buildings without diiiculty, and the sash mounting and operating parts are inclosed or concealed so as to avoid form ing obstructions, and the structure presents a neat appearance.

rllo these and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification:

ln the accompanying drawing Figure 1 is an elevation of a easement constructed in accordance with the present invention, the same being viewed from the inner side.

lFig. 2 represents a vertical section through the easement, the sash being shown in closed position.

Figs. 7 and 8 are detail views showing the bearlng for the operating worm, and the related parts. i

Similar parts are designated by the same reference characters in the several views.

Casements constructed in accordance with the present invention may be installed' in buildings of various kinds', it being understood that modifications and changes inithe construction and arrangement of parts may be made to suit different requirements. The preferred embodiment of the invention is shown 1n the accompanying drawing vand w1ll be hereinafter described in detall, a1- though equivalent constructions are contemplated and will be included within the scope of the claims. y

The easement, as shown, embodies a frame comprising vertical side rails 1 and 2, a' top rail 3, and a bottomrail or sill 4. The top and side rails are formed with a rabbet 5 at the outer side of the frame, and a stool 6 is tted on the top of the sill 4:, the e'sash frame 7 being adapted to fit into the rabbet and against the outer edge of the stool to form a suitable weather-tight joint. The sash may be of any suitable constructionand, as shown, it is provided with a lass pane 8. In the resent instance, the sas is pivoted at its right-hand side and the vertical rail 2 of the easement frame is provided with a rib 9 to engage the outer side of the sash frame and thus providea good weather-tight joint at this point.

According to the present invention, the

` sash is supported or carried by a pair of sash mountings 10 and 11. The upper -mounting 10 comprises a plate or bracket which is attached to the upper portion of the sash frame by a pivot in 12 and is attached to the upper ra11 3 o the easement frame by a pivot pin 13, the latter coperating with a plate 14 which is fastened by screws or other suitable means to the under side of the top rail 3. The lower mounting 11 is likewise connected to the sash by a pivot 15 and it is connected to the sill or lower member of the caselnent frame by a pivot pin 16 which extends through a plate 17, the latter being secured by screws or equivalent means to the upper side of the sill.

Means is provided whereby the sash may be secured to the sash mountings so that tne sash will swing in unison with the swinging movements of these sash mountings about the pivots 13 and 16, or the sash may swing relatively to the sash mountings on the pivots 12 and 15. Preferably, and as shown, an arm 18 extends downwardly from the mounting 10 and a similar arm 19 extends upwardly from the mounting 11, these arms being shaped or adapted to lie flatwise against the outer side of the sash frame when thelatter is in position to swing with the sash mountings. Means coperative with these arms serves to fasten the sash frame to the swinging mountings. As shown, the arms 18 and 19 are provided with slots 20 and 21 and with recesses 22 and 23 extending crosswise of the slots, and bolts 24 and 25 are extended through the sash frame and have heads 26 and 2T on their outer ends and thumb-nuts or equivalent tightening means 28 and 29 on their inner ends to cooperate with the inner side of the sash frame. By loosening the bolts and turning the heads 26 and 27 into alinement with the slots 20 and 21, the heads of the bolts may pass through the slots of the arms 18 and 19, and

hence the sash frame may then be swung about its pivots 12 and 15. On theother hand, when the sash frame is swung into a position to bring its outer side against the arms 18 and 19, the heads 26 and 27 of the bolts, after passing through the slots 20 and 21, may be turned, and after these heads have been seated in the recesses 22 and 23, the thumb-nuts 28 and 29 may be tightened, thereby fastening the sash frame to the upper and lower sash mountings, and the sash will then swing in unison with the swinging movements of these mountings about the pivots 13 and 16 as an axis. Ordmarlly, the sash frame will be fastened to the sash mountings, swinging motion of the sash mountings in one direction about the pivots 13 and 16 as an axis bringing the sash into the closed position, as shown by the full lines in Fig. 3, while swinging motion of the sash mountings in an opposite direction about the same axis will swing the sash either into the fully open position shown by the dotted lines in Fig. 3, or any desired intermediate position. When, however, the

vsash is unfastened from the arms 18 and 19 of the sash mountings, the sash may then be swung about the pivots 12 and 15 of the sash Lacasse mountings as an axis. For example, the sash may be swung into the position shown by the dot-and-dash lines in Fig. 3, which position enables cleaning of the sash to be accomplished with facility and, also, the sash may be swung into the position shown b v the dash lines in Fig. 3, the sash then lying in a plane parallel to the wall of the building, or substantially so, and thus reducing to a minimum the obstructing action of the sash at the outer side of the building. This latter adjustment of the sash is advantageous where the easement is fitted in the wall of a building which faces a porch.

The present invention provides simple and ecient means for operating the sash with facility and ease, thereby enabling the sash to be adjusted by feeble or infirm persons. Preferably, and as'shown, the lower sash mounting 11 is formed with a gear sector or quadrant 30 which is concentric with the. pivot pin 16, and a worm 31 is provided which coperates with the quadrant. The worm is fixed to an operating shaft 32, and a box 33 provides bearings 34 and 35 for the shaft and also serves to substantially inclose the worm. The box may be made in two sections, as shown, to facilitate its manufacture and the assembling of the worm and shaft therein, and the box may be set in a recess 36 formed in the upper side of the sill 4. 1n order to balance the weight of the sash and thus facilitate the movements thereof, a track 37 is formed on the sash mounting 11 at the outer side of the quadrant 30, this track being concentric with the axis 16, and a roller 38 is mounted in the box 33 and coperates with the under side of the track, the roller and track sustaining substantially the Weight of the sash and thus relieving the pivots 13 and 16 of the strain and correspondingly diminishing friction incident to the swinging movements of the sash. The operating shaft 32 is extended inwardly through a channel or bore 39 formed in the top of the sill. and through a molding 40 such as is,- usually fitted to the inner side of the sill beneath the stool. Preferably, and as shown, an escutcheon 41 is fitted into the molding and serves as a bearin to steady the inner end of the operating s iaft. The inner end of the operating shaft preferably has a squared or angular end 42, and a crank 43 with a correspondingly shaped hub is removably fitted to this squared or angular end of the operating shaft, the crank having an inwardly projecting handle 44. The quadrant and the oper ating shaft are covered and concealed by the stool 6, the lower side of the stool and the upper side of the sill being appropriately recessed to provide pockets within which these parts may operate. -By rotating the shaft 32 by manipulation of the crank 43, the worm 31 operates upon the quadrant 30 to swing the sash about the pivots. 13 andl as an axis. By this operation, the sash may be swung either into open or closed position, or any intermediate position. When, however, it is 'desired to clean the sash, the same is vfirst swung to its fully open position, the

bolts which fasten the sashto its mounting are unfastened, and the sash is then swung into substantially theposition shown by thev sition, and by unfastening the sash from the sash mountings, the sash may be swung into the position shown by the dash lines. 0W- ing to the use ofva worm anda ear segment for e'ecting the ,opening and c osing movements of the sash, the operating shaft has such a mechanical advantage over the sash that the sash may be lswung into thedesired position by the application of a relatively light force to the .operating crank.

' Preferably, and as shown, the crank is removable from the shaft and is capable of being applied in reverse position thereon. This is advantageous in that it removes the crank as 'an obstruction at the inner side of the easement, and by providing an opening or bore to receive the handle 4A lof thev crank when the latter is applied` in reverse position on the shaft, the 'crank will lock the operating shaft from rotationand hence lwill,

act as a lock to retain the sash either'vin position or in any other desired posiclosed tion.

A easement constructed in accordance with the present invention is not only capable of operation with ease and facility, but it presents the further advantage that the sash may be operated without the necessity or removing or otherwise `disturbing the window` screen or shade whensuch are used.

l clalm as my invention l.v A easement comprising a casing, a sash to t therein, a'p'air of mountings pivbtally supported on the casing and pivotally connected to the top and'bottom edges respec-4 tively ofthe sash at points intermediate the width of the s-ash, each mounting having an c arm arranged to engage the outer face of the sash, and devices to coperate with said to iit therein, a pair of mountings pivotallyy supported on the casingand pivotally connected at the top and bottom edges respectively of the sash at points intermediate the width of the sash, each vmounting having an` arm arranged to engage the outer faces of the sash, and bolts extending throughsaid arms and the adjacent portions of the sash for detachably securing the sash to said mountings. v
